Domain mapping problem!

I’m using WordPress MU Domain Mapping plugin and have set it up as per instruction & edited its DNS settings to actually point to the server IP or CNAME or whatever allows me do to make the domain connect to the server. For me, I just give it a new A record with the server IP in it. But when I’m hitting the new domain, it redirects me to “default.secureserver.net” & it says “Sorry! This site is not currently available.”

I’m using Godaddy Shared Hosting (doesn’t support wildcard DNS) so it’s a subdirectory installation.

Any Idea???
